Question

I’m trying to make some kind of pagination system.

Each page has a maximum of 4 elements that came from a DB.

Each page is surronded by a div (div id=’p1′ class=’pagedemo _current’). So I have the following:

$i=0;
$pag=0;
$arr = array();

while($rowNews = mysql_fetch_array($rsNews)){
    $i++;
    $arr[$i] = $rowNews;

    if($i%4==1){
       echo "div id='p1' class='pagedemo _current'"
     }

  ...show content...

    if($i%4 ==0 ){
       echo"</div>"; //close the tag of class="pagedemo"
    }

}//end of while

This open a div when the i is 1; 5 ; 9…. and closes when is multiple of 4 (4; 8; 12…)
But I also want to close the div when $i its the last number, ie: If there’s only 6 results I want to close the div after the 6th element.

I’m not accomplish it

Any ideas??

You need to be able to count how many rows are in your mysql result. Then compare it with your iterator.

$i=0;
$pag=0;
$arr = array();

$total = mysql_num_rows($rsNews);
while($rowNews = mysql_fetch_array($rsNews)){
    $i++;
    $arr[$i] = $rowNews;

    if($i%4==1){
       echo "div id='p1' class='pagedemo _current'"
     }

  ...show content...

    if($i%4 ==0 || $i == $total){
       echo"</div>"; //close the tag of class="pagedemo"
    }

}//end of while
